Thanks for the info SomeJaneInRI.
I think i may have a good guess what it may be then KingKong.
As i mentioned i tested the PH in the tap water i am using and from the chart it is way over 7. Maybe this is causing a nute lock out. Is N one of the nutes that can be locked out by high PH? Sorry if that sounds a bit silly, but as i say i am learning. |
